JOSEPH BOUTEILLE, or Pants, FRANCE.

ELECTRIC INTERRUPTER.

Applicatioii li led December 18, 1917. Serial No. 207,763.

To all whom, it may concern:

Be it known that I, Josnrn; BOUTEILLE, a citizen of the Republic ofFrance, of 51 Rue Lacordaire, Paris, France, engineer,

have invented new and useful Improvements in Electric Interrupters,which. improvements are fully set forth in the following specification.

This invention relates toapparatus for mechanically interruptingelectric currents between two electrodes, and is more particularlyapplicable to magnetos .for the ignition of internal combustion engines.t has for its object to provide a simple apparatus which can run atrelatively high speeds with little wear either of the elec tric contactsor of the parts in movement.

According to this invention a spring mounted member or projection actedupon,

by'a cam and a spring mounted electric contact are .supportedseparately,but are connected in their movement by an intermediate piece, such as afreely moving suitably guided rod. Preferably the projection and thecontact are mounted on two diflerent springs which may be formed of asingle blade or of a U shaped spring whose central portion is rigidlyfixed.

The accompanying illustrative drawing shows a front elevation of anapparatus made in accordance with this invention.

1 is a' plate turning with the armature of the electric machine to whichit is fixed; it carries on one side of its axis an electricallyinsulated metal piece 2 made fast by a screw 3. A U shaped spring L'isrigidly fixed to the metallicpiece 2; the free ends of the springsupport the fiber projection 6 (which receives its necessary movementfrom one or more cams 6 fixed to the frame of the machine) and theelectric contact 7 which is preferably formed of platinum. The rotatingplate 1 carries on the other side of its axis a metallic projecting part8 which supports a platinum electric screw contact piece 9 and alsoforms a guide for an intermediate freely movin rod 10 which coordinatesthe movement 0 the two branches of the spring 4. 11 is a recess for acarbon brush. i

The apparatus works as follows:

In the position of the parts as illustrated the projection 5 is notaffected by the cam 6 and the two electrodes 7 and 9 are in con-Specification of Letters Patent.

or moving, thus deflecting one branch of the springwhich willdraw withit, through the intermediary of the guided rod 10, the other branch ofthe spring carrying the electrode 7; the electrode 7 thus becomesseparated from the electrode 9, and the current which was establishedwill be broken; and so on each time the pro ection 5 passes in front ofthe cam;

It will be understood that the drawing is only given byway ofillustration and any other usual mechanical arrangements may beemployed. Thus an assemblage of cams may be rotated which will in'turnact upon a fixed projection. 3
